Abstract
Description
Die Erfindung betrifft einen Aktuator nach dem Oberbegriff des Anspruchs 1.The invention relates to an actuator according to the preamble of claim 1.
Aus der
Der Ventilhebel ist an einem Ende
als Lagerrohr ausgebildet, das an seinen beiden Seiten in Lagerböcken gelagert
ist. Die Drehstabfeder ragt mit ihrem einen Ende in das Lagerrohr
und ist im Bereich des einen Lagerbocks mittels einer Kerbverzahnung drehfest
mit dem Lagerrohr verbunden. Mit ihrem anderen Ende ist die Drehstabfeder
auf die gleiche Art in einer Haltebuchse drehfest eingespannt, die
ihrerseits an einem Zylinderkopf der Brennkraftmaschine angeflanscht
ist. Die Haltebuchse weist eine definierte Drehlage auf, welche
die Vorspannung der Drehstabfeder bestimmt. Durch Verschwenken der
Haltebuchse in Langlöchern
ist ihre Drehlage und damit die Vorspannung der Drehstabfeder einstellbar.
Die Betätigungseinrichtung
des Gaswechselventils ist aufwändig
und bean sprucht einen großen
Bauraum. Ferner ist das Einstellen der Drehstabfeder schwierig und
ungenau. " In der
Indem die Drehstabfeder an einem Ende fest mit dem Anker verbunden ist und am anderen Ende unter Zwischenschalten einer Aufnahme mit dem Träger verschweißt ist, besteht nach dem Zusammenbau in diesem Bereich keine Möglichkeit zum Nachjustieren. Das Justieren erfolgt ausschließlich über die Elektromagnete, deren Magnetjoche am Halteträger verschraubt sind und in einer speziellen Montagevorrichtung gegenüber dem Anker ausgerichtet werden können.By the torsion bar at a End is firmly connected to the anchor and at the other end under Interposing a recording with the carrier is welded, There is no possibility after assembly in this area to readjust. The adjustment is done exclusively via the Electromagnets whose magnetic yokes are bolted to the support bracket and in a special mounting device aligned with respect to the anchor can be.
Aus der
Der Erfindung liegt die Aufgabe zu Grunde, bei einem gattungsgemäßen Aktuator-die Einstellung einer Mittenlage zu erleichtern und sicherer zu machen. Sie wird gemäß der Erfindung durch die Merkmale des Anspruchs 1 gelöst. Weitere vorteilhafte Ausgestaltungen ergeben sich aus den Unteransprüchen.The invention is the task Basically, in a generic actuator-the Adjustment of a center position to make easier and safer. It is according to the invention solved by the features of claim 1. Further advantageous embodiments emerge from the dependent claims.
Nach der Erfindung stützt sich die Drehstäbfeder über ein plastisch verformbares Element am Gehäuse oder an einem relativ zum Gehäuse unbeweglichen Bauteil, wie beispielsweise Zylinderkopf oder Zylinderkopfhaube ab. Zweckmäßigerweise geschieht dies über einen Einstellhebel, der mit einem Ende drehfest auf der Drehstabfeder sitzt. Zwischen dem anderen Ende des Einstellhebels und dem Gehäuse ist das plastisch verformbare Element mittels einer Einstellschraube eingespannt. In vorteilhafter Weise umgibt das plastisch verformbare Element in Form einer Hülse die Einstellschraube.According to the invention is based the torsion bar spring over plastically deformable element on the housing or on a relative to casing immovable component, such as cylinder head or cylinder head cover from. Conveniently, this happens over a setting lever, which rotatably with one end on the torsion bar spring sitting. Between the other end of the adjusting lever and the housing is the plastically deformable element by means of an adjusting screw clamped. Advantageously, the plastically deformable surrounds Element in the form of a sleeve the adjusting screw.
Das plastisch verformbare Element ist in seiner Länge so ausgelegt, dass die Drehstabfeder in der Gleichgewichtslage, die ungefähr der energetischen Mittenlage entspricht, eine geringfügig größere Vorspannung erhält. Durch die Einstellvorrichtung, z.B. in Form einer Einstellschraube, wird das plastisch verformbare Element so weit zusammengedrückt, dass die Drehstabfeder die genaue Vorspannung erhält, die erforderlich ist, damit der Schwenkanker seine Sollwertstellung als Gleichgewichtslage einnimmt. Die Hülse und die Einstellschraube sind einfache Bauelemente, die wenig Bauraum beanspruchen und einfach zu handhaben sind.The plastically deformable element is in its length designed so that the torsion bar in the equilibrium position, the approximately the energetic center position corresponds to a slightly greater bias receives. By the adjusting device, e.g. in the form of an adjusting screw, the plastically deformable element is compressed so far that the torsion bar gets the exact preload needed with it the swivel armature assumes its set point position as equilibrium position. The sleeve and the adjusting screw are simple components, the little space claim and are easy to handle.
Weitere Vorteile ergeben sich aus der folgenden Zeichnungsbeschreibung. In der Zeichnung ist ein Ausführungsbeispiel der Erfindung dargestellt. Die Zeichnung, die Beschreibung und die Ansprüche enthalten zahlreiche Merkmale in Kombination.Further advantages arise the following description of the drawing. In the drawing is an embodiment represented the invention. The drawing, the description and the Claims included numerous features in combination.
Der Fachmann wird die Merkmale zweckmäßigerweise auch einzeln betrachten und zu sinnvollen weiteren Kombinationen zusammenfassen.The skilled person will conveniently consider the features individually and to sinnvol len further combinations.
